In order to not destroy the performance of battery, the service life of battery is not shortened, for each battery, in charging process
In, the current voltage of each battery is preferably not more than limiting voltage, i.e., as few as possible appearance overcharging state.
Due to the specificity of each battery, the residual voltage of each battery is different during battery consumption, even if fill simultaneously
The speedup of the voltage of each electric battery is also different, and preferable charged state is that the current voltage of all batteries is identical, together
When charging after, the speedup of each cell voltage is also identical, and the voltage of all batteries reaches the full quota voltage charging complete.
Because the specificity of each battery, preferable charged state are difficult to realize, during charging, the dump energy of each battery
It is different, if charged simultaneously, certainly will occurs that the voltage of a certain battery is very low, and overcharging state has occurred in other battery, use
When, it may appear that short -board effect, the utilization rate of battery reduce, and cause the usage time of whole battery module to reduce.
So the present embodiment provides a kind of equalization methods in charging process, the concept of charge balancing index is introduced,
The process of charging detects to the voltage of each battery, by the current same standard charging of charge balancing index of each battery
Equalization index E marks are contrasted, and the charge balancing index of current a certain battery is less than balanced this battery of explanation of standard charging
Charge balancing index is poor, it is necessary to be charged first to it, and this equalization methods can avoid short -board effect, improve battery
Utilization rate.
Reference picture 4, in order to be better understood from the charge equalization method of the present invention, battery in battery module is defined as 4
The battery of series connection, i.e. m=1, n=5.
Setting is when starting to charge up, and the voltage and position relationship of each battery are (P (1,1), V (1,1)=3), (P (1,2), V
(1,2)=1), (P (1,3), V (1,3)=4), (P (Isosorbide-5-Nitrae), V (Isosorbide-5-Nitrae)=0)),
V is total=V (1,1)+V (1,2)+V (1,3)+V (Isosorbide-5-Nitrae)=8, V flat=2,
The charge balancing index of each battery is respectively E (1,1)=1.5, E (1,2)=0.5, E (1,3)=2, E (Isosorbide-5-Nitrae)=0, takes mark
Quasi- charge balancing index E mark=0.75, E (1,2), E (Isosorbide-5-Nitrae) illustrate the charging of the two batteries less than E marks in this case
Equalization index is very poor, less than standard charging equalization index, it is necessary to preferentially be charged to P (1,2), P (Isosorbide-5-Nitrae).This charging modes can
To ensure within the fewer charging interval, the service efficiency of the short -board effect increase battery of nearly possible supplement battery.
It should be noted that marking the selection range of numerical value for E, if E targets are chosen, numerical value is too small to be occurred, in battery
So obvious for there is the voltage induced of the battery of short -board effect in dynamic charging process, in the bigger time all to
Battery module carries out overall charging, and the battery for causing to have reaches overcharging state soon and stops charging, and some batteries were had a deficit
More, the utilization rate of integral battery door module is not high；
If it is excessive that E targets choose numerical value, occur, in the dynamic charging process of battery, charge balancing module is short to having
The voltage induced of the battery of plate effect is more sensitive, tired always in individual other one or more in the main charge circuit most of the time
Individual battery charging.
Show by many experiments, during E marks=0.75, a preferable charge balancing effect can be reached, charge efficiency compared with
Height, the utilization rate of battery module is also higher after charging complete.
In the present embodiment, T1 chooses 2 minutes, and T2 chooses 3 minutes.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements done etc., should be included within the scope of protection of the invention with principle.
